hi guy,

i'm not sure why we need this distinction, i.e. if it cannot do useful work, is it not effectively unavailable? OTOH, i think this parameter is a good idea anyway because the current spec (SI-3) does not include anything that directly tells you if the service is currently available or not, which seems like a major oversight (or am in missing something?).
